If the truck driver thought he was being unfairly inconvenienced by the golf cart moving too slowly, that could elicit an emotional response which is apparently what happened. Note that I did not say his response was appropriate, just explainable.

If the golf cart should not have been on the road or should not have been holding up traffic, then it would be annoying at a minimum and could have easily resulted in THEM getting the finger.

But cutting in front of them and hitting the brakes was just stooped and there's no excuse for that.
He's lucky the slow-pokes in the golf cart were not armed.
